Are these actual? If fictional is allowed (and maybe even if not), what about light bulb? (As seen on "Scrubs," but I just read today that that script element was based on an interview with a physician.) Edit: True story. Seen here, on sionnach's cited page.

I also read once, years ago, in "Weird News" or something, about a gentleman who suffered from... er... piles... and was in the habit of using a World War II-era bullet to... er... remedy the situation... and once it got stuck and he had to go to the hospital.
